Answer: 615.44 cm²
Step-by-step explanation: When solving this problem the formula that you need to know is that area = π r².
The 14 cm that they are giving you is the radius of the circle, and π equals 3.14. So, in order to solve this the formula is:
Area = 3.14 x 14²
Area = 3.14 x 196
Area = 615.44 cm²
Answer:
C
Step-by-step explanation:
If you fill in x=0, you are left with the y intercept. In the picture you can see it must be larger than y=10. This invalidates answer A and D.
The x-coordinate top of the parabola ax²+bx+c=0 is given by y = -b/2a, so immediately we can see -b has to be positive. This leads you to answer C because -9x implies b=-9, and --9 is positive.
